3Native Google Search

Google Now is a smarter search engine that combines reams of data from your past Google searches, rankings, clicks, etc, with data from mobile sensors (like geolocation and time zone). For example when you open Google Now you’ll find widgets for the weather where you are. Performing a Google search through Jelly Bean will now yield more relevant, personalized results than through a desktop.

6Intelligent Widgets

9Smarter Keyboard

The stock keyboard is now backed by a better predictive engine that suggests words before you type them. Voice input also works offline now which is quite an amazing feat, though I found it very tedious to use.
